摘要

在低温下,计算了二维电子简并系综在异质结构阱中的霍尔迁移率随温度的特征依赖性。除了与远离子杂质的电子相互作用和表面粗糙度外,该研究还适当考虑了一些由于数学简单而经常被忽略的因素。这包括电子-声子碰撞的非弹性和真实声子分布。对AlGaAs/GaAs、AlGaN/GaN和AlInSb/InSb等异质结构的结果表明,上述细节的考虑显著改变了整体特性,使其与实验数据非常吻合。

On some comprehensive study of the Hall mobility of an ohmic ensemble of two-dimensional electrons confined in a quantum well of a heterostructure at low lattice temperatures
The characteristic dependence of the Hall mobility upon the temperature of a degenerate ensemble of two-dimensional electrons in a well of heterostructure has been calculated in some broad details, for the ohmic field region, at the low temperatures. Apart from the electronic interactions with the remote ionized impurities and the surface roughness, the study also duly considers some factors which are often ignored for mathematical simplicity. These include, the inelasticity of the electron-phonon collisions and the true phonon distribution. The results thus obtained for heterostructures like AlGaAs/GaAs, AlGaN/GaN and AlInSb/InSb, show that the consideration of the above details significantly changes the overall characteristics, and makes them agree quite well with the experimental data.
